Features of functions:
( 1) Simple
C is a simple language in the sense that it provides structured approach (to break the problem into parts), rich set of library functions,data types etc.
(2) Machine Independent or Portable
Unlike assembly language, c programs can be executed in many machines with little bit or no change. But it is not platform-independent.
(3) Mid-level programming language
C is also used to do low level programming. It is used to develop system applications such as kernel, driver etc. It also supports the feature of high level language. That is why it is known as mid-level language.
(4) Structured programming language
C is a structured programming language in the sense that we can break the program into parts using functions. So, it is easy to understand and modify.
(5) Rich Library
C provides a lot of inbuilt functions that makes the development fast.
(6) Memory Management
It supports the feature of dynamic memory allocation. In C language, we can free the allocated memory at any time by calling the free()function.
(7) Speed
The compilation and execution time of C language is fast.
(8) Pointer
C provides the feature of pointers. We can directly interact with the memory by using the pointers. We can use pointers for memory, structures, functions, array etc.
(9) Recursion
In c, we can call the function within the function. It provides code re usability for every function.
(10) Extensible
C language is extensible because it can easily adopt new features.
(11) Re-usability
C functions are used to avoid rewriting same logic/code again and again in a program.
There is no limit in calling C functions to make use of same functionality wherever required.
We can call functions any number of times in a program and from any place in a program.
(12.) Modularity:
A large C program can easily be tracked when it is divided into functions.
The core concept of C functions are, re-usability, dividing a big task into small pieces to achieve the functionality and to improve understandability of very large C programs.
(13.) Debugging becomes easy:
Bug (error) fixing becomes easy, so that without disturbing the other code directly we can fix the bug.
in case of large program with lacks of code, debugging becomes difficult in case if you don't use functions
